How we score →Yay
4 experts · Moderate agreementWhat the gurus are saying
A 10% niacinamide serum that visibly reduces pores and controls oiliness earns praise as an excellent pick for anyone with combo or oily skin. The formula is deliberately simple (just niacinamide and little else), which keeps the price genuinely affordable, and that simplicity makes it a solid entry point for people just starting skincare. One job done well, and done affordably.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
